Although Yuan Fei's mission this time is to guard this place, it is better to guard the entry of others.

He had already checked this cell several times, and it was almost covered with all kinds of immortal patterns, which could be said to be indestructible, even if the Demon Lord made a move, there was no possibility of breaking it, and he basically became an ornament.

Yuan Fei was also happy to be idle.

At first, he looked around with some curiosity, and took a closer look at the prison, but he didn't find any figures or anything unusual, and after a long time, he was a little uninterested.

So he sat cross-legged on the stone platform and meditated.

said that he was meditating, but in fact, he had already secretly cultivated the Mixed Yuan Immortal Duel.

You know, he has to be guarded in this prison for a hundred years, so naturally he can't just wait like this.

As for the first half of the Mixed Yuan Immortal Duel, Yuan Fei had already sorted it out, with a total of four layers, and began to cultivate.

So far, he has cultivated the exercises to the third level. Thinking about it, with the help of many pills, it is not impossible to cultivate the first half of the exercises to the fullest in a hundred years.

As for Yuan Fei's incarnation and spirit beasts, his cultivation has also made great progress. Especially the ghost baby, which is the body of the yin, and during the period, because of the mutation, the demon body can be said to be like a fish in water, and the cultivation has increased dramatically, almost catching up with his master.

Yuan Fei's eyes were slightly closed, and he pinched the immortal decision in his hand, and there was a golden immortal text hidden on the surface of his body.

What Yuan Fei didn't notice was that when he was cultivating the Mixed Yuan Immortal Duel, the Demon Suppression Tablet in the Heavenly Prison suddenly rippled, and a black demon dragon phantom appeared, and he glanced out of the prison in shock.

After a moment, the black dragon's gaze flickered, and then disappeared again.

On this day, Yuan Fei's eyelids suddenly twitched slightly, and he slowly opened his eyes.

Now that he has cultivated the third layer of the Mixed Yuan Immortal Duel to perfection, he can start the cultivation of the fourth layer of exercises.

However, cultivating this kind of immortal duel was extremely difficult for the tempering of the physical body, if it weren't for the fact that he had already been accustomed to this kind of pain, but the long-term cultivation still made him a little tired.

After taking the pill and relieving it for a few days, Yuan Fei did not continue to cultivate the Mixed Yuan Immortal Duel, but used the Taixu Sword Technique to polish the Immortal Yuan Power little by little, making the Immortal Yuan Power more refined and vigorous, so that he would be more sure of his future advancement to the Xuan Immortal.

But Yuan Fei hadn't been running the exercises for long, but his expression suddenly moved, and after dispersing the exercises, he turned his head to look at the prison door.

After Yuan Fei pondered for a while, he got up and walked outside the prison door, and through the iron window, he saw a black demon dragon coiled on the demon suppression monument.

"Flame Black Dragon?" Yuan Fei's gaze swept over the black dragon, and his pupils couldn't help shrinking.

Yuan Fei's nine-yuan true fire was integrated into the remnant soul of the scorching black dragon, and he was naturally no stranger to it.

It's just that he never thought that this demon dragon was actually imprisoned in this prison.

The thoughts in his heart were spinning rapidly, and he had already roughly guessed that the demon dragon in front of him should be the existence of the Flame Black Dragon, otherwise he would never have made the Kuixing Demon Venerable so cautious.

However, why the Kuixing Demon Venerable wanted to imprison the Flame Black Dragon here was not something he could speculate.

Just now, when Yuan Fei was running the Taixu Sword Technique, someone suddenly heard in his ears, and he discovered the existence of the Demon Dragon.

Although Yuan Hong had already told him not to come into contact with this dragon, Yuan Fei was full of doubts in his heart, and after hesitating for a moment, he couldn't help but say in a deep voice: "I don't know what happened to the predecessor Chuanyin. ”

"Daoyou is a disciple of Kuixing Demon Venerable?" Yan Xuan glanced at Yuan Fei with a pair of bloody eyes, and said with a smile.

"Yes, in the lower Biqing. Yuan Fei said in his heart.

"Haha, Daoist friends don't have to hide it, the deity doesn't believe that the Kuixing Demon Venerable will accept a Terran monk as an apprentice. After Yan Xu laughed, he suddenly said something that made Yuan Fei's expression change greatly.

"I'm afraid that my predecessors have been imprisoned in this prison for a long time, and their minds are a little confused, and they are dignified demons below, how can they be any Terran monks. Yuan Fei tried his best to suppress the shock in his heart, and said with a gloomy face.

"Hehe, if the deity is not mistaken, Daoist friends should be cultivating the Taixu Sword Technique, right? This kind of immortal duel can only be cultivated smoothly by the Dao body of the human race, and it is difficult for other alien races to cultivate even if they are forcibly cultivated, not to mention that Daoyou has already cultivated to the sixth level of Dacheng. Yan said confidently.

"What is too void sword trick, what the predecessors said is simply nothing. If the seniors talk nonsense again, they will have to pay homage to the master, and then the seniors will be in trouble. Yuan Fei snorted coldly.

"Although the Taoist friend is retribution, it is not the deity who is in trouble. Yan Xu sneered.

Seeing this, Yuan Fei's face was gloomy like water, and his eyes were fixed on Yan Xi.

After a while, Yuan Fei took out the key from his arms, opened the cell door with a "click", and slowly walked to the front of Yansha.

Although Yuan Fei didn't know how the other party knew his identity, in order to protect Mingzhe, he could only get rid of this evil dragon.

If the flame was in its heyday, Yuan Fei naturally didn't dare to do anything to him, but now that he was trapped in the Demon Suppression Monument, even though he still had Xuan Immortal cultivation, it was useless, and it was easy to kill him.

Moreover, once he absorbed the primordial spirit of this demon dragon, he thought that he could directly advance to the Xuan Immortal even if he didn't have to take the pill.

Thinking of this, Yuan Fei's killing intent grew, and with one hand, he flipped over and grabbed the Kun Spirit Blade in his hand.

"What, Daoyou wants to kill people and kill people? Hehe, even the Kuixing Demon Venerable can't help me, do you still have any immortal forbidden techniques that can't be achieved?" Yan snorted disdainfully.

"Although the cultivation is not high, there are still some means to deal with the body of the primordial gods. Since the Yansha seniors are suspicious, the juniors are offended. After Yuan Fei smiled at the corner of his mouth, he suddenly raised his hand and slapped it on his chest.

With a "snap", a black light shot out from its chest, enveloping its body like lightning.

"Yin and Yang Qi! Impossible, how can you, a small true immortal, control such innate qi. Seeing that his body couldn't move a bit, and that he was in a posture of being devoured, Yan Xun exclaimed in disbelief.

Yuan Fei was also moved in his heart.

Not only did he urge the Yin and Yang Creation to be admired many times, but he still didn't know much about the origin of this black light, but now he actually knew it from Yan Xi's mouth.

As far as he knows, the two qi of yin and yang are the innate qi of the same level as the qi of chaos, and the qi is divided into yin *** and has the power to control life and death.

At this point, Yuan Fei smiled and said, "Since the seniors know the origin of this Xuanguang, they won't have any doubts, right? ”

"Hehe, this is indeed the two qi of yin and yang, but the breath is much weaker, but it can't really threaten the deity. Yan Sha was a little panicked at first, but quickly calmed down.

Since Yan Sha said such a big thing, Yuan Fei no longer stayed, and after reciting a few words of incantation, the black light suddenly rolled, and he was about to forcibly devour the body of Yan Sha Yuan Shen.

But the next scene surprised Yuan Fei.

Although the black glow flickered wildly, the body of Yansha was only a little distorted and deformed, and it seemed that it was involved in it, but most of its body was still coiled on the Zhentian Demon Monument without moving.

Seeing this, Yuan Fei pinched the magic trick in his hand, and the black glow disappeared in a flash.

And Yansha's body gradually returned to normal, but his face was also very ugly, obviously because he had just felt a lot of trouble because of the resistance to the sun.

"What's the matter? The deity didn't deceive fellow Daoists, did it?" Yan sighed and said with a smile.

"The seniors don't need to be strong, even if it's really as the seniors said, if it takes a long time, the body of the seniors' primordial gods will be gradually weakened until it comes to naught. However, the seniors have no grievances with Zaixia, and Zaixia doesn't want to kill them all. Yuan Fei glanced at Yan Yan a few times, and said with his arms folded over his shoulders.

That's true. But once something really goes wrong with the deity, the Kuixing Demon Venerable will immediately sense it, and then the Daoist friends will not be able to escape. The demon's eyes narrowed slightly.

"Are the seniors too underestimated? Being able to blend into the Demon Palace, even the Kuixing Demon Venerable can't see the slightest clue, and it's not easy to escape away. Yuan Fei was not afraid at all.

"Daoyou is really bold, and the deity is indeed not wrong. In this way, the deity will not be hidden. If the deity is not mistaken, there should be no follow-up exercises for the Taixu Sword Technique cultivated by Daoyou, right?" Yan Sha not only did not show any anger, but instead showed a mysterious smile.

"How can you see it?" said Yuan Fei with a slight frown.

After Yan Xu laughed, he looked at Yuan Fei and said word by word: "I can't hide it, the follow-up exercises of the Taixu Sword Technique are in the hands of the deity." ”

Hearing this, Yuan Fei's body trembled slightly.

He had already heard the Xingyue Fairy mention that there were several other Heavenly Immortals who snatched the Taixu Immortal Record back then, and it seemed that this Demon Dragon Yansha was one of them.

Moreover, he was detected by the other party just by revealing a trace of breath, which also showed that Yan Sha was extremely familiar with this Taixu Sword Technique.

"The seniors aren't joking, right? the seniors have been imprisoned here all the year round, how can they get any follow-up exercises for the sword technique?" Yuan Fei looked at him with a skeptical look after his thoughts turned around.

"Hmph, the reason why the deity became a prisoner is because of an immortal record, and naturally there is also this Taixu sword technique.

Back then, the deity and several other immortal powers competed for the immortal record, but they were severely injured by a plot, and they had to use a secret method to escape. Unexpectedly, he was unlucky enough to run into Kuixing Demon Venerable, and he was trapped here.

However, the deity is not for nothing, and the seventh layer of the Taixu Sword Technique is in the hands of the deity. Of course, there are some other immortal duels and forbidden techniques, and if the Taoist friends are interested, it is not impossible to teach them to the Taoist friends. Yan Sha seemed to think of something, and after snorting, he said with a gloomy face.

As soon as he heard this, Yuan Fei couldn't help but feel a little moved in his heart.

Over the years, he has been worried about the follow-up exercises of the Taixu Sword Technique, who would have thought that this Yansha would have a seventh-layer exercise in his hands, if he could really get the follow-up exercises from his hands. Nature is the best.

However, Yan Sha has been enduring until now, and after an unknown number of years, Kuixing Demon Venerable has no way, and it can be seen that this demon dragon is not scheming, and he must not be gullible.

"What do the seniors want? In addition, the seniors have no evidence, at least let the subordinates believe it. Yuan Fei's mind turned sharply, and his face remained unchanged.
